Hi Harland,
Welcome to the forum. It seems that the neobladder and pouch-ers outnumber those with ostomy's on this board, so I'm glad for your experience with an ostomy here.
About the stones, what about that non-invasive technique, shockwave therapy? Why cut if there's another option to blast those things, is that not an option for you? I know it's expensive, but hopefully insurance would cover that, I'd think.

PS we also have an active email group that discusses things related to all stages of bladder cancer, also short on ostomates, more neo's, pouches and non-invasive tumors, but lots of comraderie.
